npm unable to resolve dependency tree for @4.0.0 (angular-devkit/architect)

[squio]

This issue looks exactly like #437 again; adding --force does work

This is caused by the mismatch of angular-devkit/architect versions @^0.1200.0 vs @^0.1202.2
The newest patch release appears to work just fine.

At the same time it is rather scary to run any npm update with the force flag everytime.

I understand there is little the ionic team can do here, still reporting so others are aware of the issue.

This works for me: npm i --save-dev "@angular-devkit/[email protected]

Hi @mhartington is this dependency fixed to ^0.1200.0 for some reason or a PR changing this would be welcomed?

I too am having a similar issue going from angular 11 to 12 on Ionic 6 rc.0. I also feel using the force flag is risky...

I have the same issue.

@ionic/angular-toolkit v4.0.0 has a peer dependency to @angular-devkit/architect ^0.1200.0 which means it's only able to fetch @angular-devkit/architect v0.1200.5 at the moment (instead of v0.1202.10), so if you try to upgrade to Angular v12.1.X or v12.2.X you'll get this error.

Please will you issue an update to support @angular 12.2.x. By not doing so and using --force to install @ionic/angular-toolkit, it results in npm reporting critical compatibility errors, for example npm audit fix won't work, adding cordova plugins etc all keep reporting @ionic/architect-toolkit as breaking compatibility.

To avoid this, I tried downgrading @Angular-devkit/architect to 0.1200.10. The problem with this is that this version fails if NPM is above 7.5.6 or Node above 14.0.0. However if you read the Ionic documentation regarding installing/upgrading Ionic, the first thing it says to do is make sure you have installed the latest version of Node and NPM.

I appreciate that this problem is caused by the non-standard semver numbering of @angular-toolkit/architect but that does not help developers like me.

I know I'm repeating myself but please issue an update to fix this issue.
